This project has been possible thanks to the work of almost fifty participants and collaborators, distributed over various countries of North Africa and Southern Europe. In essence, we have thoroughly revised the content of the Guía de los Árboles y Arbustos del Norte de África (Charco, 2001) and numerous improvements have been made to the text, photographs and maps. Also, new species, genera and even families have been added, now that Egypt and a large part of Sudan are included. The following list names all the participating experts, sorted by their country of origin.

Other important participants and collaborators
In the first place, it is worth highlighting the Mediterranean Cooperation Center of the International Union for Conservation of Nature (IUCN Med), for promoting the project, and the MAVA Foundation, for financial support. We would like to give special thanks to engineer Ahmed Salama, Director of the Nature Conservation Section of the Egyptian Environmental Affairs Agency (EEAA), Ministry of Environment of the Republic of Egypt. He facilitated our access to the exploration of several natural regions of Egypt. In the case of the Wadi Gimal Protectorate, this allowed us to be accompanied by environment agent Ayman El-Gharabawy and his teammates, Hassan and Hussain, the latter from the Ababda tribe. In the Saint Katherine Protectorate we were warmly welcomed by Mohamed Hemeda, who allowed us to explore the Protectorate, joined in the field by zoologist Amir Shaloufa, botanist Asmaa Ali and the Bedouin guides Seleem and Salim. In the rest of the country, everyone we met in the field was always kind and ready to help. We do not recall every name but we are very thankful to all of them.
We also received help from specialists for the description of certain species. The Egyptian specialist Karim Abdelhai Omar, for example, helped us with the species Rosa arabica, that he knows so thoroughly. The help of Lola Almagro and Gonzalo Martínez Salcedo was very valuable in the transcription of texts. Silvia Jurado Güeto offered valuable help in map design. The most interesting common names for species from the Algerian Sahara were shared by Nacéra Boucheneb and Boudjema Bouzidi, nomad sedentarirez from Béni-Abbès (Béchar region).
We would also like to give special thanks to the translators, François Lassurguere, Patricia Malcolm and Mercedes Paz that, with their professionalism helped us to identify and correct small but numerous mistakes throughout the texts. And last but not least, we owe much gratitude to Catherine Levassor. This botany professor selflessly made a first translation of the text to French, in 2006, which remained unpublished due to financial reasons. Now that we have the means to publish it, we dedicate the French version of this new edition to her.
